Noise on a rectifier output is three different problems wearing one name: low-frequency ripple from the filter, high-frequency switching noise from the converter, and ringing from the layout. Classifying the symptom first decides the fix. This guide walks the classification, the probing, the rectifier-specific sources, and the cures. Symptom Classification: Ripple vs Switching Noise vs … Read more
The on-board charger is moving in three directions at once: bidirectional power flow, higher bus voltages, and higher power density. Each trend changes the rectifier story, and this guide traces the three causal chains and their device implications. The Bidirectional Trend: V2X Changes the Power Flow Vehicle-to-everything (V2X) capability turns the OBC from a one-way … Read more
Automotive lighting moved from halogen to LED and now to matrix and adaptive systems, and the Good-Ark device families are part of the power-stage roadmap, and each step changed the power stage: more current, faster dimming, tighter protection, and a hotter lamp module. This guide traces the evolution and its device implications. The Lighting Evolution … Read more
PV and energy storage systems are changing the electrical environment for power semiconductors: higher-power modules, 1500 Vdc architectures, SiC penetration in inverters, and bidirectional storage stages each shift what a diode must carry. This guide maps the trends and their component-selection implications. Module, String, and Storage Architectures The architecture decides where the diodes sit. A … Read more
A failed TVS is usually the protection telling you something: the rating was wrong for the waveform, the placement let the inductance win, or the pulse count exceeded the part’s capability. This guide covers the failure modes, the three classic mistakes, and the redesign checklist. (Last modified date: August 31, 2026) TVS Failure Diagnosis — … Read more
Surge damage leaves evidence before it leaves a part: a melted die, a cracked package, or a slow leakage drift. Reading the signature and tracing it to the event — inrush, lightning coupling, or load dump — is what turns a failed part into a protection upgrade. This guide covers the signatures, the tracing, and … Read more
A second source for a power semiconductor is an engineering decision, not a purchasing shortcut: the alternative must be qualified electrically, thermally, and mechanically before it earns a place on the BOM. This guide covers the qualification, the cross-reference, the lifecycle management, and the direct-manufacturer relationship that keep a supply strategy honest. (Last modified date: … Read more
Ten amps continuous in a sealed automotive housing is a thermal case study: the forward-drop loss at temperature, the junction calculation, and the copper-and-housing countermeasures. This guide walks the worked case from loss to verification, with the parameters to confirm from the official datasheet. (Last modified date: August 31, 2026) The Method in One Sentence: … Read more
The AWSS10H60 is a 10 A, 60 V Schottky barrier rectifier in an eSGC (TO-277) package from Good-Ark, positioned for high-current automotive lighting. It is the 60 V cell of the 10 A AWSS row, and its full electrical specifications are confirmed with the supplier. This article covers the thermal-first positioning, the ratings, and the … Read more
In an automotive lamp module, the solder joint under the TO-277 exposed pad is the weakest connection: thermal cycling and vibration fatigue it long before the die fails. This guide covers the mechanism, the footprint and process rules, the qualification thinking, and the design checklist. Why Solder Joints Fail in Lamp Modules The lamp module’s … Read more
